About Morrisburg

Morrisburg's HVAC profile is shaped by two things most contractors don't account for: the Seaway and the wind off it. When the original village was relocated to higher ground in 1958 to make way for the St. Lawrence Seaway, the new lots were laid out on an exposed plateau between the river and County Road 2. The result is that homes along Lakeshore Drive and the surrounding grid take direct wind load in winter that homes inland in Williamsburg or Brinston don't see — heat loss through windward walls is measurably higher, and undersized furnaces here struggle on the coldest 10 days of the year while oversized ones short-cycle on the milder weeks. Right-sizing matters more in Morrisburg than almost anywhere else in our service area. The relocated heritage homes from the Lost Villages also share a quirk: many were moved on rollers with their original chimneys repointed in place, and we still pull cracked heat exchangers tied to inadequate draft on those flues. On the cooling side, summer humidity rolling off the river puts Morrisburg in a different latent-load category than the rest of SD&G — a two-stage AC or a variable-capacity heat pump dehumidifies far better than a single-stage unit ever will, and we won't quote single-stage cooling in this town anymore. Lastly, Morrisburg is almost entirely propane or oil — natural gas hasn't been built out south of Highway 401 — which is why nearly every cold-climate heat pump we install in South Dundas goes into a Morrisburg or Iroquois home.

Why Morrisburg Homeowners Choose Alpine Air

We Account for Seaway Wind Load

Most contractors size furnaces from a square-footage chart. We do a full Manual J that factors wind exposure on your specific lot — critical for Lakeshore Drive, Highland Drive, and any home on the south side of County Road 2.

Two-Stage Cooling Standard

River humidity makes single-stage AC a comfort failure in Morrisburg. We default to two-stage or variable-capacity systems that actually pull moisture out — your house will feel cooler at 24°C than it used to at 21°C.

Oil-to-Heat-Pump Conversions Done Right

We've converted enough Morrisburg homes off oil to know which floor plans need a backup electric coil and which can run heat-pump-only down to -25°C. We'll size against your last three years of fill-up records, not a generic estimate.

Local Emergency Response

We're based in Williamsburg, about 10 minutes north on County Road 31. When your heat goes out and the wind off the river is dropping the effective temperature to -35°C, that response time matters.
